It seems that Wolfgang Sawallisch’s tenure with the Philadelphia Orchestra is coming to an end none too soon. The 79-year-old maestro, who has been battling severe fatigue lately, managed to muster the strength to conduct his final Carnegie Hall concert with the Fabulous Philadelphians this week, but his exhaustion has forced him to pull out of this week’s concerts back in Philly, and the orchestra is making no guarantees that he will even be on hand for his farewell concerts next week, or for a taxing 3-week tour beginning immediately thereafter. All this is unfortunate, says Peter Dobrin, but “Sawallisch’s last Carnegie concert will stand as a stunning and poignant musical memento.”
